Start Chromium and open about:plugins. "Chrome PDF Viewer" should now view; it may need to be enabled.

Note: As a new version of Chromium will not update Template:Filename it may become incompatible. Thus and with respect to possible security fixes it is advisable to update both at the same time.

mozplugger

To use mozplugger, install Template:Package AUR from AUR.
Follow similar instructions as described in Firefox Tweaks to set up the PDF app you wish to use with mozplugger-chromium.

kpartsplugin

To use KParts Plugin, install Template:Package AUR from AUR.
The plugin should be able, among other things, to open PDF files inside Chromium using an embedded Okular instance.

Certificates

Chromium uses NSS for the certificate management. Certificates can be managed (including added) by going to Wrench -> Preferences -> Under the Hood -> Manage Certificates.

Tips and tricks

Controlling Memory Usage

Chromium offers some command-line options to help control how efficient it is with system memory, by determining how often it should release memory back to the operating system. It is done with the flag --memory-model=X, where X is either high, medium, or low. Setting it to high makes chromium never release memory. Medium makes it reduce its working set of the memory when switching tabs, and low makes it reduce its working set when switching tabs and when the browser is not actively being used. In my experience, running chromium with --memory-model=low can actually improve performance as well, though your mileage may vary. --Falcata 06:07, 26 November 2010 (EST)

Link file manager to "Show in folder" function

When you are using a window manager such as Openbox in combination with a file manager like Thunar instead of a DE, this function of Chromium may only show the directory tree inside Chromium. However to show the file in the folder using your file manager instead, install Template:Filename.

Icons not shown in download tab

You may find that Chromium shows icon placeholders (icons representing broken documents) instead of appropriate icons in its download tab. The likely cause is that you have not installed a desktop environment.

Remedy this by installing GNOME icons:

# pacman -S gnome-icon-theme

Cache in tmpfs

For SSD users, it is nice to have the cache of Chromium in a tmpfs, but there is no need to have the whole profile in a tmpfs (see below). Someone posted here a solution for this.

Profile in tmpfs

The default Chromium profile is located in Template:Filename. This profile can be relocated to an available tmpfs filesystem, including Template:Filename, or Template:Filename for improvements in application response as the the entire profile is now stored in RAM. Another benefit is a reduction in disk read and write operations, of which SSDs benefit the most.

Simple bash script to automate the process

Use the following Bash script to automatically move your Chromium profile to Template:Filename and keep it synchronized.

Enabling experimental features

To enable experimental features of Chromium like WebGL and rendering webpages with the GPU, type "about:flags" in the Chromium address bar and enable features you want.

Search Engines

You can make sites like wiki.archlinux.org and wikipedia.org easily searchable by first executing a search on those pages, then going to Options>Preferences>Basics and clicking "Manage" in the "Default Search" section. You can then, for example, "Edit" the Wikipedia entry and change its keyword to "w". Then, you can search Wikipedia for "Arch Linux" from the address bar by simply entering "w arch linux". "?" is a hard-coded keyword for Google search (it will behave differently from the other keywords). It allows you to easily search for things like "/bin/bash".
